Information structure of power supply system and spacecraft regulation and control equipment

Improving the quality of automatic control systems is an important problem in many areas. This issue is particularly relevant in systems requiring an increased level of reliability, such as control systems for space equipment including power supply systems. Power supply systems must fully meet the need of a spacecraft in electric power required for regular flight program performance, which implies the increased requirements for its reliability and quality of its operation. The article considers functional and informational structure of spacecraft power supply systems. The principles of data exchange between the elements of regulation and control equipment with the power supply system are described and the hierarchical structure of the power supply control system elements is built. The current approaches to the automatic systems of control and management of spacecraft power supply systems are regarded. Based on these data, the algorithms of power supply system control are analyzed using the example of battery charging and discharging algorithms. The phenomena which are not accounted for when building the algorithms are considered. The means to improve the algorithms for controlling battery charging and discharging by introducing new parameters to track the degree of battery degradation are proposed, and the means of intellectualizing the algorithm are considered. A proposal is made to intellectualize the control system using a neural network trained on the spacecraft onboard telemetry.
